Summary:
A new technology which can be used to improve the omni-directional radiation pattern of polyhedron array is studied with mutual coupling compensation. Firstly, the mutual coupling between array elements is expressed in a matrix form, which can be obtained by the orthogonal method. The mutual coupling is compensated by calibrating the excitation of array elements. Then, a tetrahedron array consisting of eight dipole elements with operating frequency of 800MHz is designed and simulated in order to obtain an omni-directional pattern. In this way, the omni-directional radiation property of polyhedron array can be improved greatly. The roundness of the omni-directional pattern of 1.271dB can be obtained for the array antenna designed, with 1.5dB improved. The numerical results show that the method is accuracy and efficiency.
